The WTX and WTX-D Series is a selection of harnesses, buoyancy cells and accessories which offer unparalleled versatility due to the modular nature of the whole system. Each component can be configured into a highly technical rig for those trained to push the limits, or scaled down to make a travel friendly set up suitable for any diver. This popular accessory is ideal when it becomes necessary to add additional weight to your rig. Using the included hardware, they may be bolted to the WTX harness or to the SureLock™ Attachments. SureLock™ is the best mechanical weight release system in the industry today. A simple click is all that is needed to engage the weights and a simple pull on the handle to release them.
